Link Control Protocol

dropped and an outgoing call to the

be made to re-establish the link.

 

 

Callback CP

After acceptance from both ends the

Microsoft's Callback Control Protocol

incoming call is dropped and an

 

outgoing call to the number configured

 

in the Service will be made to re-

 

establish the link.

 

 

Extended CBCP

Similar to Callback CP however the

Extended Callback Control Protocol

Microsoft application at the remote end

 

will prompt for a telephone number. An

 

outgoing call will then be made to that

 

number to re-establish the link.

 

 

The following points must be noted for Callback functionality

Callback for an incoming call is configured on a RAS and for an outgoing is configured on the Service.

For an incoming call the Callback option need NOT be set on the Service. Setting Callback on a Service allows the IPNC to negotiate Callback when initiating the call.

For all Callback types an intranet service type must be used.

To support a mixed environment where some incoming calls do not require Callback a separate RAS’es must be configured (with a unique DDI) with and without Callback enabled.

Certain Callback types maybe configured to circumnavigate Time profile restrictions.
